SEAMLESS TRANSMISSION OF MEDIA TRAFFIC FOR ROAMING MOBILE TERMINALS DURING HANDOFFS

摘要

Methods for seamless transfer of media traffic for roaming mobile terminals (20) during hard handoffs from one base station system (21) to another (25) are described. In one embodiment, a base station controller (24) forwards media traffic after handoff occurs to a second base station controller (26) where the mobile terminal is currently registered. The second base station controller listens for media traffic from the first base station controller on one port and for traffic from the remote equipment on a second port. When traffic starts to arrive on the second port, the first port is released
